93C

93C is a designation that can refer to several different things, primarily in the context of integrated circuits and semiconductors. Most commonly, it refers to a family of serial electrically erasable programmable read-only memory (EEPROM) chips manufactured by various companies, including Microchip Technology and STMicroelectronics. These chips are used for non-volatile data storage in embedded systems, where they retain data even when power is removed. They typically interface with microcontrollers via a serial bus like I2C or SPI. The "93" in the designation often indicates the organization of the memory, such as 16K bits of storage arranged in a 256-word by 8-bit format, or similar configurations.

Beyond EEPROM, "93C" might also appear as part of a model number for other electronic components, such as certain microcontrollers or specialized integrated circuits. The specific function and characteristics would depend on the manufacturer and the full model designation. Without further context, the EEPROM interpretation is the most prevalent. These memory chips are essential for storing configuration settings, calibration data, or small amounts of program code in a wide range of consumer electronics, automotive systems, and industrial equipment. Their low power consumption and serial interface make them a popular choice for many embedded applications.
